1. Important Safety Instructions
SAVE THESE INSTRUCTIONS:
This manual contains important safety, installation and operating
instruction for the remote meter.
General safety information
Please inspect the MT11 thoroughly after it is delivered. If there is
any damage, document this with photos and contact the shipping
company or seller for assistance.
Please read this manual carefully before installing the product and
pay close attention to the safety information.
Keep the MT11 away from rain, dust, vibrations, corrosive gas and
intense electromagnetic interference.
Do not allow water to enter the remote meter.
There are no user serviceable parts inside the remote meter. Do not
disassemble or attempt to repair it.
The MT11 is only compatible with DM series charge controllers.
Please confirm before purchase and installation.

2. Overview
The MT11 remote meter is an accessory which is compatible with
the DuoRacer (DM series) MPPT solar controller. It can monitor the
running data and working status of the controller, set the battery type
and temperature units, and reset the generated energy counter.
Features:
Automatically identify and display the type, model and relevant
parameter data of compatible controllers.
Real-time display of the operational data and working status of the
connected device in digital, graphical and textual forms by a large-
screen multifunctional LCD.
Three touch buttons are quick and easy to operate.
No need for external power supply. The connected charge controller
supplies the power for MT11.
The meter can browse the controller’s parameters, set the
battery type and temperature unit, and reset the generated
energy counter.
Real-time display of fault information of the connected devices.
Long communication distance via RS485.

equalize duration is 0 to 180min, and boost duration is 10 to 180min.
2) The following rules must be observed when modifying the value of the
parameters in User battery type (factory default value is the same as sealed
type):

A. Over Voltage Disconnect Voltage > Charging Limit Voltage ≥ Equalize
Charging Voltage ≥ Boost Charging Voltage ≥ Float Charging Voltage >
Boost Reconnect Charging Voltage.
